Naming rich family in French Revolution

Hi berries! I've really been struggling with naming this family for my story so I figured you would be the best people to help!
I have named my main character Alexandra "sasha" Persephone (insert second middle name) and I would like all the characters names to be traditional first, the children to have Greek mythology second, traditional third. I am also really struggling with surname so if you have any ideas that would be great!

Can you specify the family's nationality? Without that information, it's impossible to contribute realistic names. It would be very unlikely for a French family at the time to have foreign names like Nicholas and Alexandra (rather than Nicolas or Alexandrine). Similarly, an English or German family would not have French names.

Well, I don't think I can add much to that! I like Sibylle for the mother, though, and Nicolas for the father. Camille fits the sweet ten year old, too. No opinion on the others.

“I read books when I was a kid, lots of books. Books always seemed like magic to me. They took you to the most amazing places. When I got older, I realized I couldn't find books that took me to all the places I wanted to go. To go to those places, I had to write some books myself.”
